HOME ORAFTSHOP OUTFIT.

Application filed larch 28, 1928. Serial No. 264,255.

This invention relates to home craftshop Outfits. is to provide an improved lathe bed structure which has the features of strength and durability associated therewith.

Another feature of the invention relates to novel adjustments of the tail stock with relation to the lathe bed to permit the proper ilignment of the dead center with the opposed head stock spindle.

Still another feature of the invention relates to the novel motor mounting with the attachment base and means for securing the latter to the lathe bed, switch mechanism being housed in the base for operating the front and rear parts of the double shaft which is journaled in the motor bearing.

Still another object of the invention relates to the detachable machine support and to the adjusting means associated therewith for adjust-in any suitable machine such as a rip saw ta le or a scroll saw on said support, the machine being driven by any suitable driving means from the rear shaft of the motor.

Referring to the various figures on the drawing, the numeral 1 represents the lathe bed which consists of the spaced angularly shaped members 2 which are secured to the casting leg structure 3 by means of the bolts and nuts 2'. The spaced members form a slot or gui'deway 4'for the tail stock indicated by the numeral 5, the tailstock having the conventional dead center 6 which is operated by the hand wheel 7.

The tail stock is slidably mounted upon the lathe bed for lateral or transverse movement. There are integral projections or lugs One of the objects of this invention 8 extending from the body of the tail stock into the space bounded by the angularly shaped members,

meral 12 which extend into the slot or guideway 4, the projections and tail stock being slidably associated with the pins for permitting lateral adjustment of the former. As a means for securing the tail stock in adjusted position, the set screws 13 are provided which extend into the projections 8 and contact the pins 12. WVlien the tail stock is in adjusted position laterally, it can be slid along the guideways and clamped in any desired position by means of the clamp 9 which bears against the washer 10 and is secured to the body by means of the screw threads 11.

Positioned as an extremity of the lathe bed is the head stock which includes the m0- tor 14, a double shaft 15 being journaled in bearings therein. On the rear part of the shaft is mounted for rotation a pulley 16 and on the front part a face plate 17 which is secured to the shaft by means of a set screw 17 the motor being provided with thrust bearings 18 for taking up the shock.

The motor 14 is detachably secured to a switch housing 19 and rests in an arcuate portion thereof, the motor being bolted thereto by means of the bolts 20. The housing is detachably secured to the lathe bed by means of the bolt 21 which threadedly engages the arcuate portion and which extends downwardly thru the slot 4, the bolt being in contact with the washer 22 which engages the lathe bed members 2. The electric switch for turning the current on and off is designated by the numeral 23 and the cord and plug for engaging a lamp socket by the numeral 24. The cord extends thru a bushing formed in the side of the hollow base or housing 19.

Extending substantially at right angles to the lathe bed is a base or support 25 which is supported by the cast iron legs 26 integrally associated therewith, and the former is detachably secured, at another portion, to the angularly shaped members 2 by means of clamping screws 27. Slidably mounted upon the base or support is the rip saw table designated by the numeral 30 and this table is secured to the base or support by means of bolts 29 which ride in slots 28 of the support. The numeral 31 designates the conventional circular saw and this saw is driven by the motor, the drive being taken and extending thru these pro ections are pins designated by the nu- D thereon.

In Fig. 8 is shown the spur center which can be substituted for the face plate whenever the occasion warrants. The spur center 33 can be secured to the shaft 15 by means of the screw 34. The lathe rest and all necessary tools can be supplied with the outfit but since they form no part of the invention they have not been shown or described.

The operation will be apparent from the above description. Whenever it is necessary to align the parts 15 and 6, the screws 13 are unloosened and the tail stock shifted laterally on the pins 12 until center 6 is in alignment with shaft 15 of the head stock, the screws are then clamped into place and the tail stock is in adjusted position laterally. Since the pins 12 are slidably mounted in the slot or guideway 4, the tail stock can he slid longitudinally into the proper position and the latter clamped into position by means'of the clamp 9. The face plate or spur center, as the case may be, is then mounted upon the front part of the double motor shaft and secured into position by the respective set screws. The thrust bearings 18 take up the shock when the work is inserted between the face plate and part 6. As described, the motor can be detachably secured to the arcuate seat of the housing 20 and the entire housin removed by unscrewing the bolt 21. W en the cord is plugged into a lamp socket the double shaft 15 revolves and the appropriate tools are used for operating upon wood or other material.

It will be noted that a rip saw, scroll saw or any other mechanism can be used or substituted for the mechanism 30. When the situation arises the base or support 25 can be attached to the angularly shaped members 2 by the intermediary of the clamps 27 and the table 30 secured in any desired adjusted position by means of the bolts 29 which extend thru the slotted portion of the base. It may be desirable at times to tighten the flexible belt which drives the machine and the adjustable feature will provide for this exigency.

It will be apparent from the above description that a very practicable and convenient home craftshop outfit has been provided which can be sold on the unit plan. The

basis of the outfit is the bench wood lathe which is fitted with the double shaft motor of either one fourth H. P. or one third H. P., as the case ma be. This machine is provided with the woo turning chisels, chucks, grinding wheel etc. which elements form no part of this invention.

By providing a base with the angularly shaped members 2 an important advantage is secured in that the bed can be constructed of any length. By providing the tail stock with a lateral adjustment more effective work can be secured because the opposed live and dead centers are, brought into proper alignment. The removal of the motor can be facilitated by the particular arcuate seat structure and the novel housing forms a convenient place for the insertion of the switch, cord and plug.

Whenever necessary the attachment can be used in conjunction with the lathe structure. Due to the detachable feature of the support, the attachment or mechanism can be removed at will and due to the adjustable mounting of the attachment on the support the proper tension can be placed on the belt to accommodate different types and sizes of attachments'mounted thereon.

From a consideration of the above it will be apparent that a cheap, durable and readily assembled home craftshop outfit has been provided which may be" bought on the unit plan and the parts readily and conveniently assembled by the user. The motor can be bought separately and the other attachment readily attached to the lathe bed by means of the support.

What Iclaim is In combination, a lathe bed having members in spaced relation, a tool support positioned at right angles to said lathe bed, means for detachably securing the former to the latter, a head stock. detachably secured to said lathe bed at one portion thereof, said head stock including a motor having a shaft, a tool adjustably secured to said tool support, means associated with a part of said tool and the motor shaft for driving the tool, a tail stock slidably mounted for longitudinal movement on the lathe bed, said tail stock having a dead center and integral lugs extending thru the slot formed by the spaced members, said in s being less in cross sectional diameter tilan the width of the slot, pins mounted in the lugs and extending transversely across the space formed bv the slot,

said lugs being slidably'associated with respect to the pins, means for adjustably securing the lugs to the pins and a clamp asso-
